Environment Checker Investigation

Investigate environment and configuration issues that cause failures in specific contexts.

Investigation Checklist

Configuration Verification

• Compare actual configuration values against expected defaults
• Check for missing required environment variables or config keys
• Identify configuration override precedence conflicts
• Verify config file format and encoding are parsed correctly
• Look for environment-specific config that was not applied

Platform Differences

• Identify OS-specific behavior differences causing the failure
• Check for path separator, line ending, or case sensitivity issues
• Verify runtime version compatibility across environments
• Look for locale or timezone settings that affect data processing
• Check for architecture-specific issues in native dependencies

File System & Permissions

• Verify file and directory existence at expected paths
• Check read, write, and execute permissions for the running process
• Identify symlink resolution failures or broken links
• Look for disk space or inode exhaustion conditions
• Check for file locking conflicts with other processes

Network & Connectivity

• Verify DNS resolution and endpoint reachability
• Check for proxy, firewall, or VPN interference
• Identify timeout values that are too aggressive for the environment
• Verify TLS certificate validity and trust chain
• Look for port conflicts or binding failures on the host
